here is a simple design to have more analog ports for EZB without using a second EZB
pretty simple design and works perfect
use a cd4051 or cd4052 multiplexer chip anone analog port and 3 or less digital ports
can hook up as much as 8 analog devices,4052 does 4 analog devices
circuit is super simple to make only chip and EZB
SAME can be done with digital ,only need a digital multiplexer chip
any diagram or sample program would be appreciated
Thank You
havent dont any scripts on it yet,all you are doing it selecting witch input analog port you want to read on EZB using the truth table on cd4051
if you need to know the pin # i can tell you it,no other parts are needed, can add on the chip a .1 mfd for noise,like when you use any type of digital or analog chip its vcc to vdd where the capacitor goes on close to the the chip as you can
Hobbytronics 12 channel I2C servo Controller
there are many servo controller boards with I2C port
like this one with 20 ports
20 servo controller board with I2C
none really for analog, there is I2C A-D but only one port and there is a chip for digital ports using I2C i have that chip ,forgot the number but will find the chip i think PC8754
Can you connect many different device to I2C port in parallel since there is only one port?
thats what great about using I2C devices
